Osmo Decking Oil is especially good for protecting, feeding and maintaining dense exotic hardwood decking such as Teak, Ipe and Balau.
This highly refined oil is very thin meaning that it has excellent penetration properties, is very water-resistant, dirt repellent and easy to maintain and re-finish when required.
Can also be used on softwood decking and most untreated garden furniture. Osmo deck oil dries to a smooth satin-matt finish.
Osmo Decking Oil provides a durable protective finish for all types of softwood and hardwood decking, smooth or grooved. Water-repellent, Osmo decking Oil reduces the risk of swelling and shrinkage and can be over-coated with a single coat of Osmo Anti Slip Decking Oil 430 if required.
Note: Osmo 'clear' decking oil does not offer any UV resistance so although the wood will be protected from moisture, cracking, splitting and warping, it will not prevent decked areas from turning grey or silver over time.
There are ways to apply wood oils... and ways not to! Why not read our series of three blog posts about getting your garden decking into tip top condition? Here's the third in the series, covering wood oil application.
Decked areas must be clean, dry and frost-free. Old paints, varnishes and other surface coatings must be removed by sanding. Old applications of oil based treatments or stains need to be cleaned or lightly sanded. If sanding, use a 120 to 150 grit sandpaper and remove all traces of surface dust.
New wood: If possible apply first coat on all sides of the wood before installation. Hardwoods with an especially high content of oil, leave to weather for about 2 to 3 months (in winter up to 5 months) or wipe over with White Spirit to degrease the surface.
For additional protection against blue stain, rot and mildew, pre-treat with Osmo WR Base Coat 4005 or with Osmo Wood Protector 4006 (biocide-free).
Osmo Decking Oil is ready to use straight from the tin and can be applied with a brush or cloth. Stir well before application and use a brush or soft lint free cloth to apply a thin, even coat of oil along the wood grain. Wipe off any excess when finished and leave to dry. Apply second coat as above or alternatively, apply a single coat of Osmo Anti Slip Decking Oil 430 if required.
The type and age of the timber can have a dramatic impact on how much oil the wood needs. As an example, softwood decking that is old will probably require more oil than a relatively new hardwood deck that probably still retains a fair amount of natural oil.
To test how much oil your decking needs, apply one coat, allow to dry, then apply a droplet of oil in a corner. If the droplet of oil soaks into the wood then a further coat can be applied. Repeat this process until the droplet of oil sits as a bead on the surface of the wood and no longer soaks in to the timber. This is an indication that the timber has absorbed as much oil as possible and doesn't require any more.
Surfaces treated with Osmo Decking Oil are very easy to clean and maintain. Just use a moist cloth with Osmo Wash And Care 8016. Particularly persistent stains can easily be removed with Osmo Liquid Wax Cleaner 3029. If necessary, apply a further coat of Osmo Decking Oil onto areas that have become worn or dull due to high foot traffic.
Thinning and Cleaning
Application brushes and equipment can be cleaned with white spirit.
This product can be stored up to 5 years or more if the tin is full and tightly closed. Store in dry place. If thickened by frost it will regain its normal consistency under normal temperatures within 24-36 hours.
If there is an amount left over after application, it is recommended that the remaining oil is poured into an alternative container of the same volume e.g. 1 ltr of oil left pour into a 1 ltr drinks bottle or other secure container. By filling the alternative container to the rim and securing an air tight lid, the remaining oil will stay in good condition for much longer than if left in a container half filled with air.
Osmo decking oil is safe for human, animal and plant when fully dried.
Q. Is there a specific time on how long an oiled deck will last before it needs re-oiling?
A. Unfortunately not. The reason for this is that the elements such as wind, rain and sun all have a degrading effect on the amount of oil in the wood. For that reason, every deck will be different because of location, shelter, weather patterns and general wear and tear.
Q. Is Osmo Decking Oil UV resistant to protect the colour of the decking?
A. Osmo decking oil is available in three variations, clear, black and grey. While the black and grey colours do offer UV resistance due to the pigments suspended in the oil, the clear variation does not. Decking treated with the clear version of Osmo Decking Oil will therefore be susceptible to the natural grey / silvering of the timber over time.
In short, the darker the colour, the better the UV protection. In the case of this product, grey offers more protection than clear and black offers more protection than grey.
Allow 10 to 12 hours drying time between coats and the final finish. Drying times may vary depending on the decking type, air temperature and humidity.
